Unlike other formats, PDFs maintain their layout and typography, allowing users to share documents confidently, knowing they will appear as intended. PDFs can contain images, text, hyperlinks, forms, and even multimedia elements, making them a universal go-to for document sharing.

- Forms: PDF forms allow for user input while maintaining the original layout, making them ideal for applications and surveys.
Advantages of Using PDF Files
PDFs offer numerous advantages that make them the preferred choice for many individuals and organizations:
- Universal Compatibility: PDFs can be opened on any device or platform without the need for specific software.
- Security Features: Users can protect PDF files with passwords, restricting access to sensitive information.
